 - trace individual fns
 - show file and line num in output
 - deep trace (inside fn)
-- profiling features?
-  - use joda
 - wrap args that are funcs
  - and deep search values for funcs?
 - wrap returns that are funcs

- rendering strings is deadly slow?
- use pmap all over the place?
  -- add pmap mode to walk18???
x ws-load bug???
- profiling features?
  - use joda
- cursors
   - bisect recording trees to find bugs
- split ns and fn name in trace rec and output
